To all whom it may concern.'

Be it known that I, GEORGE E. MnssiNoER, a citizen of the United States, residing at Birmingham, in the county of Jefferson and .State of Alabama, have invented certain new spurious coins and prevent the introductin of other coins until a spurious coin has been removed.

A further object of my invention is to enforce the complete operation of the macliine after the proper coin has been introduced and before another coin can be inserted.

lVith these several objects in View, my invention comprises the details of construction and arrangements of parts which in their preferred embodiments only, are hereinafter more particularly described and illustrated in the accompanying drawings 2, showing the coin mechanism in plan.

Fig. 6 is a cross section on the line c-c of Fig. 2.

Similar reference numerals refer to similar parts throughout the drawings.

I have shown my invention mounted Within a casing formed of threef longitudinal sections comprising a back 1 having angled side flanges 2, and two side members 3 and 4 which are both angled in cross section and adapted to overlap and to be connected together by screws 5. The rear edges of the sides are adapted to be lapped by the back flanges 2. and the back is provided with a forward extending tongue 6 which projects vof articles 21 to be delivered.

under the top 7 of the casing and is adapted to be engaged by a lock S controlled by a key 9. The back has a top flange 10 which overlaps the top 7. The top 7 and bottom 11 of the casing are formed integral with the side member 3 and the bottom has at its rear edge a down turned lip 12 which is adapted to interlock with the upturned lip 13 of the back member 1. The side member 4 of the casing is provided at one of its forward bottom edges with a flange 14 which is connected by a screw 15 to the front wall 16 of the casing which is a part of the frame member 3. The side walls 3 and 4 are increased in thickness at the base of the machine and a discharge chute 17 is provided in the front wall 1G, having its upper end disposed horizontally and having as extensions of its rear or bottom wall integral spaced bars 18 which extend to the rear of the back and have uptuined ends 19 which project under rear guide ianges 2O for the pocket that receives the stack These articles are preferably in the form of square packages of gum, matches, or other commodities and are charged into the rectangular chamber provided in the upper portion of the casing, the lower article resting upon the arms 18. A weight follows the articles down and is provided in its forward face with a notch 23 for the purposes hereinafter described.

Below the bars 18 l dispose a transverse rocker shaft 24 having its intermediate portion squared and l mount fast thereon the oscillatory ejector 25. This is mounted on the shaft betweena coiled spring 2G on one side and a ratchet wheel 27 o'n the other side. The outer end of the shaft projects through the side wall of the Icasing and through a plate 28 forming the outer wall of the compartment in which the coin control mechanism is disposed and which plate is riveted ,o otherwise attached to the side plate 4. T .e shaft, lwhere it passes through the plate 25, is rounded and takes a bearing therein. A handle 9.9 is attached tothe shaft end to turn same.

The ejector 25 consists of an elongated sleeve having thereon two integral spaced segment shaped ejector arms 30 disposed in parallelism and adaptedwhen swung upwardly to pass between the plates 18. These ejector arms are similar and are shown in side elevation in Fig. 1, `Where it will he seen that they are provided at their article engaging corners with a lip 3l which swings up through a l@groove in the bach ineinber l and engages the rear edge of' an article 2l. rlhese ejectors are also notched out at 83, which notches in ejecting position, see Fig. 3, swing; over the inner Wall of the chute 17. One end ot the spring ZG is connected to the casino; and the other to the outer end of an arni 30 and it serves to hold the latter normally in retracted position, as shown in Fig. l.

' The ratchet 27 is 'tast on the shaft 2e with the ejector and comprises a set of ratchet teeth 34 which extend about a part of its periphery.the toothed portion terminating at each end in a notch The periphery of the ratchet Wheel between the notches 35 and on the opposite side from the teeth 341 is plain. 'A pointed dctent 3G is pivotally mounted on the stud bearing 37, screwed into thevall. 3 and a spring 3S also connected. 'to said Wall and to the rear end of the detent to hold it in neutral position, that is to say, pointing' toward and in position to engage the teeth 34.

l provide in the side Wall above the shaft 24 a transverse narrow groove 397 see 'Figsa 4t and 5, and in this groove is mounted trans versely a detector har 40, which is mounted at one end on a screw el, the head oi? which is set opposite an opening; en? in the wall 4 to give access thereto ior the purposes olf' adjustment. .On the inner side oi the har l solder orothervvise 'fasten a i'iat spring i3 which bears against the inner Wall oi the groove 39 and forces the 'tree end of the har e() outwardly. This plate carries on its outer face a s ud disposed to the left of the shaft'i Fig. 5) and a detcnt e5 disposed to the right of the shaft and at the free end of the bar. The s'oud le is rounded While the detent i5 is adapted to arrest the rotation o the coin disk 46 in the manner that-Will. now be described.

Fast on the shaft 24; is `mounted a circular coin disk evhich is seated in the coin chute formed in the plate 28 and, as shown in Fig. 2, it .projects above the open front side of the coin slot il?, see Fig. 2. The coin dish e6 is provided with a notch i8 in its periphery which stands opposite the coin slot when in coin receiving position and which. is semicircular in its lower part and has the exact dimensions of the coin to be used. The disk e6 has on its right side a pair of open# ings e9 and 50 spaced from the shaft center the saine distance yof the detent The Spad ill is alsdspaoed approximately the saine. distance from the shaft center asl the center of the coin When seated in the pocket. The periphery ci the disl is reduced on one side to form spaced stop shoulders 5l and 52 which engage a stop 5S and when the disk has been given a complete ejecting movement the coin in the notch cornes opposite to and falls through an inclined slot 53 in the side member lend is delivered there# by into the bottoni or' the casing which orins the till The inner Wall of the chute 17 is pretore ably formed by a vertically adjustable 'plate 54 which slotted and held by a screw 55, passing through said slot, at the desired height so that it will support the articles so .that but one will be ejected at a time.

ln operation, after assembling` the casn ing, charging it and looking the sections by lock 8, the several articles will be supported one above the other on the arms 18 and will. be forced downwardly by the Weight 22. When a correctl coin is inserted inthe slot 17. the handie on the shaftfl; is grasped and turned to the left. lndoing this the coin, the inner .face of Which stands flush with the inner 'tace of the disk 46, will ridel Aunder the sped Llllwvithout thereby causing substantial change in the position of the detector d or permitting it to shift into a position Whereits detent /lv will engage either opening; 5:9 oro@ in the disk. lVhen the plate has been turned fully to the left, the coin is eiected and the ejector arnos 30 will have engaged the lower article and forced it out through the chute lli'. At the saine time the dog 36 will have heen sli'fted from engagement in the notch 35 ai. f. "l have ridden over the teeth 34 and stand i in the other notch 35, see liig. 3. @n reverse movement the dog 36 is rocked downwardly and permits the ratchet disk and 'the arins 30 to 'be swung hack down to initial posim tion bringing the other notch 35 opposite the dog and permitting it to right itself therein. lifter a coin has passed the detection devices. the dog 87 engages the'ratcliet teeth 34, preventing any reverse movement of the ejector either lcv the spring the oi'ierator9 and making it necessary to coniplete the turning of the ejector before new coin can be inserted. If a coin that istoo thin is inserted, vthe spring tension, on the har 40, as soon as the coin comes under its l Spud dei, 'will force the bar inwardly and its detent i5 will engage in the hole e9 and arrest the travel of the diskv Also if there is an indentation or opening at or near the center of the coin, the latter vvill pass under the spud le and permit the detent to move inwardly and engage inthe opening The rie detent operates to arrest the travel ct the disk While lthe coin is exposed and this gives' .notice that no other coin can he inserted,

1lWhen the last article has heen ejected the Weight drops and its notch 23 permits it to fall behind the ejector arms 30 and hold iii-.e coin dist'. locked in position 'to close 'lot d pre-vent the insertion of s, coin until vice relilied and'reset.
